  • Patent number: 6480501
    Abstract: A process for transporting a data cell throughout a switch fabric having a centralized switching structure and a set of distributed, generally remotely located, Switch Core Access Layers (SCAL) permitting the attachment of the protocol adapters. Remotely with respect to the centralized switching structure, the data cell which is received from a telecommunications link is divided into k logical units (LUs) and additional bytes are introduced for permitting the reservation of a bitmap field that will be used for routing through the switch core. Every LU is coded in accordance with the 8B/10B coding process. Within the centralized switching structure, the k coded LUs are deserialized and the cell clock is obtained for each cell in order to reconstitute the data cell. In addition the routing byte reservations are filled with appropriate values (bit map) for the routing process within the switch by means of an access to an entry routing table.

  • Patent number: 6421776
    Abstract: To increase the effective capacity of BIOS, an initial portion of the power on system reset (POST) code that is required to enable the system memory is stored in ROM in uncompressed form, and substantially the remaining portion of the BIOS code is stored in compressed form. Upon system initialization during a cold boot, the uncompressed portion of POST is executed from the ROM to enable the system memory, and then an image of the BIOS code is written to shadow memory. As BIOS code is needed during the remainder of the boot, the code is selectively decompressed from the shadow memory to another region of the system memory to which control is transferred. Variations based upon different boot scenarios are described.

  • Patent number: 6412111
    Abstract: A video source provides information to a communication device that results in an icon being displayed on the communications device during a preview of a television program or segment of a television program. The icon indicates to the user that a single button on a remote control or other user-controller device can be used to program the communication device, including television, video-cassette recorders, cable boxes, network computers, or the like, to display or record the desired program or program segment as the program segment is being televised or communicated. Specifically, during operation, the exact date, time, and source of the actual television program or program segment is encoded in an unused portion of a teletext data stream when the icon is present. If the communication device receives an appropriate command from its user-controlled device while the icon is displayed, a central processing unit within that communication device, saves the information together with a channel presently being viewed.

  • Patent number: 6307741
    Abstract: A portfolio computer notebook has outer hardback covers with a flexible spine. A portfolio computer is mounted to the inner surface of one of the covers, and a paper notepad is mounted to the inner surface of the other cover. Each hardback cover has a fold line that bisects it into two panels. The fold lines allow the “footprint” of the open portfolio to be reduced by approximately half of the area required by conventional portfolios without having to bend the cover back over on itself. The footprint is reducible regardless of which component the user wishes to utilize. For example, to use the computer, the user creases the hardback cover of the computer at its fold line such that half of the cover rotates and the other half of the cover stays parallel to the notepad. The computer remains mounted to the parallel half. As the computer and parallel half of the cover are moved over the top of the notepad, the two halves of the computer cover form a z-like configuration with the notepad cover.
